Water rights trading is an effective way to promote the redistribution of agricultural water saving within and among water-shortage regions. Reasonable transfer price can not only improve the income of farmers and irrigation areas, but also improve the efficiency of agricultural water use. However, the trading across industries or regions will diminish the ecosystem service value of arable land, and negatively impacts irrigation areas. This paper investigates the pricing model of agricultural water transaction, which combines water trading with ecological compensation to balance the benefits of both parties. A bi-level programming model of agricultural water trading was established for optimizing the prices and corresponding volumes of transaction across users in water markets. The context of this study is the Inner Mongolia Autonomous Region, which is a typical water-shortage region in China. Results show that adjusting price variables through the model, including transaction price and ecological compensation, led to an optimization of transaction volumes across users. The economic benefits also are optimized between the irrigation districts and industrial water users. Pricing model of water trading is also improved with ecological compensation. This study ultimately provides a useful reference for policy-makers in water-shortage regions.

Agricultural practices, specifically the use of antibiotics and other biocides, have repercussions on human, animal and plant health. The aim of this study was to evaluate the levels of Enterobacteriaceae and Enterococcus, as antibiotic resistant marker bacteria, in various matrices across the agro-ecosystem of an antibiotic-free swine farm in Quebec (Canada), namely pig feed, feces, manure, agricultural soil, water and sediment from a crossing stream, and soil from nearby forests. Samples were collected in fall 2022, spring and fall 2023 and spring 2024.

Environmental fate and aquatic risk assessment of oxyfluorfen in California rice fields.

The herbicide oxyfluorfen [OXY; 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene] recently emerged as a potential solution to combat herbicide resistance in California rice. Proposed as a preemergent applied preflood to soil, products are in development for use with OXY-tolerant rice strains. Currently, OXY is not registered for use with rice and its use in or near aquatic resources is restricted due to its high aquatic toxicity.

Selenium (Se) is a naturally occurring metalloid in soils and rocks that is released by weathering processes; it is also enriched by some anthropogenic activities, including mining and agriculture. The mechanism of Se aquatic toxicity has been understood for several decades; at elevated concentrations, dietary Se can accumulate in maternal tissues of fish and birds, become deposited into their eggs, and can potentially result in impaired embryological development. North American environmental regulations have acknowledged differences in species sensitivity and variation among aquatic environments (i.

The iChip isolation technique uses an in-situ isolation device that increases the cultivability of previously unculturable microorganisms. Microorganisms are an important source of novel chemistries and potentially bioactive molecules. However, only 1% of environmental microorganisms can be cultured using conventional laboratory methods.
